CHAIR-SEAT.

Specification of Letters Patent. Patented J 29 1920 Application filedDecember 9, 1919; Serial No. 343,455.

To all whom it may concern: 7

Be it known that I, JOSEPH P. HoLLAND, a citizen of the United States,residing at Key WVest, in the county of Monroe and State of Florida,have invented certain new and use ful Improvements in Chair-Seats; and Ido hereby declare the following to. be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to new and useful improvements in seats fordentistry, barber, and like chairs and has for its primary object theprovision of a plurality of reversible covered panels operated in unisonby .a

means so that a clean surface can be presented whenever one surfacebecomes soiled or Worn or the device can be reversed after eachoccupant, so as to render the device highly sanitary.

Another object of this invention is the provis1on of means for lockingthe panels in seat forming position, thereby preventing rotation ordisarrangement of the panels during the use of the device or whenoccupied.

Another object of this invention is the provision of a chair seat of theabove stated character which shall be simple, durable and efficient, andwhich may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination, and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which Figure 1is a plan view of the chair seat constructed in accordance with myinvention,

Fig. 2 is a longitudinal sectional View of the same,

Fig. 3 is a transverse sectional view illustrating the shape of thepanels.

Fig. 4 is a front elevation of a locking member.

Referring in detail to the drawing, the numeral 1 indicates as anentirety a reversible seat to be used in connection with dentistry,barber, doctor, and like chairs and as my invention resides in the seat,the other portions oif the chair are not shown. The

seat includes a frame 2 consisting of end vchannel members 3 and 4connected by longi- V the like secured thereon if desired. The rear endsof the bars 7 have secured thereto pinions 10 located within the rearchannel member 4 and mesh with pinions 11 secured to an operating shaft12. The operating shaft 12 is journaled in the rear channel member 4 orthe end wall thereof and one end of said operating shaft 12 projectsbeyond the frame 2 and is bent to form an operating handle 13 whereby onturning the handle, the panels will be compelled to rotate in unison forthe purpose ofpresenting another face to the seat when one face hasbecome soiled or worn. A cover 14 is removably secured to the rearchannel member 4 and is adapted to conceal and protect the pinions andoperating shaft therein.

The forward ends of the supporting bars 7 project beyond the inner wallof the front channel member 3 and are provided with squared faces 15which are adapted to contact with the walls of slots 16 formed in theupper edge of a locking strip 17. The looking strip 17 is pivotallymounted in the front channel member 3 as illustrated at 18 and hassecured thereto a spring 19 which is in turn connected to the channelmember 3 for normally holding the locking strip 17 so that thesupporting bars will be held against accidental rotation, therebyholding the panels horizontally to form an even seat. A handle 20 isformed on one end of the looking strip 17 and projects outwardly of theframe 2 so that said locking strip can be swung away from engagementwith the ends 15 of the supporting bars 7 when it is desired to reversethe panels.

A cover 21 is removably secured to the front channel member 3 for thepurpose of concealing thelocking strip 17 and the forward ends of thesupporting bars and also is adapted to give a neat appearance to thefront edge of the seat.

VVhile-I have shown and described the preferred embodiment of myinvention, it

will be understood that minor changes in construction, combination, andarrangement of parts may be made Without departing from the spirit andscope of the invention nel members, supporting barsjournaled to theinner Walls of the channel members, panels secured to the supportingbars, an operating shaft journaled in the rear channel member, meansconnecting the supporting bars in presence of two Witnesses.

to the operating shaft, upholstering secured tothe panels, a tension andpivotally mounted locking plate pivoted in the front channel member andhaving notches to receive the ends of the supporting bars for holdingthem against accidental rotation, and removable covers closing the upperends ofth channel members.

In testimony whereof I aflix my signature JOSEPH P. HOLLAND.
